apical two-thirds of posterior femora blackish, and the basal segment of 

 abdomen darker at the base. The outer cells of the posterior wings are 

 closed, as in P. delta. 



Strongylogaster soriculatus, Prov. ,5". soriculatipes, Prov., appears to 

 have been the name under which this species was first published, but the 

 Abbe' has used soriculatus in republishing, and the old name does not 

 appear in his index. 



Tenthredo grandis, Nort. This species is somewhat variable in the 

 extent of its white markings, and I have one specimen which answers 

 exactly to the T. nigricollis, Kirby, described from Newfoundland. 



Tenthredo basillaris, Prov. This species is placed in Cresson's cata- 

 logue as a synonym of T. signata, Nort. My specimens, five females, 

 of which one was determined by Provancher, are remarkably uniform in 

 their markings, and do not agree with the description of T signata, so 

 that I am disposed to retain the species as distinct. 



Tenthredopsis Evansii, Har. I have a female of this species from 

 the Rocky Mts. near Calgary, and have examined another from Colorado 

 (Gillette.) This insect is very near, perhaps identical with, Tenthredo 

 viridescens, Fourcr. {scalar is, Klug.) an European species. 



Tenthredopsis (?) annulicornis, n. sp. Female — Length, 10 mm, 

 Head black, rugosely punctured ; mandibles, clypeus and triangular spot 

 above rufous, the clypeus strongly notched ; antennas slender, two basal 

 joints and base of third rufous, apex of third, the fourth and terminal 

 three black, joints five and six pure white. Thorax with the pleura 

 coarsely punctured ; rufous above with spot on each lateral lobe of meso- 

 thorax and the scutellar sutures black ; legs rufous, tips of coxae, the 

 trochanters and posterior tarsi white, tip of posterior femora and of tibiae 

 black ; wings hyaline, nervures blackish, base of stigma white ; lanceolate . 

 cell with straight, short, cross nervures, as in Tenthredo, etc.; posterior 

 wings without middle cells. Abdomen rufous. 



Male. — Length, 9 mm. Antennas a little stouter, testaceous, rufous 

 toward base. Abdomen with apex blackish. 



The female was taken near the city on June 6th, 1891, and the male 

 on May 28th last. The antennas of the male differ in colour, and in being 

 slightly stouter, from those of the female - , but in all other respects it 

 seems to be identical. The strongly notched clypeus, and the absence of 

 middle cells in the posterior wings, would seem to refer the female to 

 Perineura, but the outer cells of posterior wings of the male are not
